Objective:
Plan laboratory, field, and modeling studies to quantify erosion processes by concentrated flows in small agricultural areas with the final goal of improving erosion control practices.

Approach:
Evaluate runoff and landscape properties such as topographic and soil profiles, and vegetative cover in field areas susceptible for ephemeral and edge-of-field gully erosion development. Complement field monitoring with laboratory measurements to characterize and quantify headcut migration, gully growth, and sediment yield from the selected areas. Description of water and sediment fluxes and sediment transport processes using models will allow the interpretation of the experimental results and their extrapolation to different conditions. Modeling efforts will cover a range of scales using analytical, BGK lattice schemes, and enhancements to the AnnAGNPS model.
